Catalysts yog cov khoom uas ua haujlwm kom ceev ceev uas muaj cov tshuaj tiv thaiv tshwm sim. Lawv ua kom tus nqi ntawm cov tshuaj tiv thaiv los ntawm kev txo qis zog. Ib qho enzyme yog qhov zoo heev piv txwv ntawm a catalyst thiab lawv ua raws cov txheej txheem hu ua 'xauv thiab qhov tseem ceeb', qhov twg cov tshuaj yog cov yuam sij thiab cov enzymes yog cov xauv.
Cia li saib qhov no, koj txhais li cas los ntawm Catalyst?
A catalyst yog ib yam khoom uas ua kom muaj tshuaj lom neeg, tab sis tsis noj los ntawm cov tshuaj tiv thaiv; li no a catalyst tau rov qab tau cov tshuaj tsis hloov pauv thaum kawg ntawm cov tshuaj tiv thaiv nws tau siv los ua kom nrawm, lossis catalyze.
Qhov thib ob, dab tsi yog qhov sib txawv ntawm cov catalysts? Catalysts thiab lawv cov kev cuam tshuam catalytic cuam tshuam tuaj hauv peb lub ntsiab hom : homogeneous catalysts , heterogeneous catalysts thiab biocatalysts (feem ntau hu ua enzymes). Tsawg dua tab sis tseem ceeb hom catalyst cov dej num muaj xws li photocatalysis, ib puag ncig catalysis thiab ntsuab catalytic txheej txheem.
Ua li no, dab tsi yog catalyst thiab nws ua haujlwm li cas?
A catalyst ua haujlwm los ntawm kev muab lwm txoj hauv kev rau cov khoom siv tshuaj tiv thaiv. Tus nqi ntawm cov tshuaj tiv thaiv yog nce raws li txoj kev lwm txoj kev no muaj lub zog ua kom qis dua li cov tshuaj tiv thaiv txoj kev tsis kho los ntawm cov catalyst.
Dab tsi yog lwm lo lus rau Catalyst?
Cov lus ntsig txog catalyst Lub zog, kev txhawb siab, kev txhawb siab, kev txhawb siab, kev txhawb siab, kev tawm tsam, spur, goad, incendiary, agitator, impulse, incitation, reactant, synergist, adjuvant, enzyme.

Dab tsi yog qhov sib piv thiab piv txwv?
Inverse proportion. Inverse proportions tshwm sim thaum ib tus nqi nce thiab qhov txo qis. Piv txwv li, ntau tus neeg ua haujlwm ntawm txoj haujlwm yuav txo lub sijhawm los ua kom tiav cov haujlwm. Lawv yog inversely proportional
Dab tsi yog qhov tsis yog hlau muab piv txwv?
Ans: Hydrogen, hydrogen, chlorine, fluorine, carbon, nitrogen, arsenic, phosphorus, selenium yog cov piv txwv ntawm cov hlau tsis muaj hlau
Dab tsi yog txhais los ntawm lub sij hawm dissociation thiab dab tsi yog ib qho piv txwv ntawm cov khoom uas dissociates?
Dissociation, nyob rau hauv chemistry, sib cais ntawm ib yam khoom mus rau hauv atoms los yog ions. Thermal dissociation tshwm sim ntawm qhov kub thiab txias. Piv txwv li, hydrogen molecules (H 2) dissociate rau hauv atoms (H) ntawm kub heev; ntawm 5,000 ° K txog 95% ntawm cov molecules hauv cov qauv ntawm hydrogen yog dissociated rau hauv atoms
Dab tsi yog qhov txawv ntawm instantaneous thiab nruab nrab ceev dab tsi yog qhov piv txwv loj tshaj ntawm kev ceev ceev?
Qhov nruab nrab ceev yog qhov ceev nruab nrab ntawm lub sijhawm. Instantaneous ceev yuav yog qhov ceev txhua qhov muab tam sim ntawd hauv lub sijhawm ntawd, ntsuas nrog lub ntsuas ntsuas lub sijhawm
Dab tsi yog qhov txawv ntawm microevolution thiab macroevolution Dab tsi yog qee qhov piv txwv ntawm txhua tus?
Microevolution vs. Macroevolution. Piv txwv ntawm cov kev hloov microevolutionary no yuav suav nrog kev hloov ntawm hom xim lossis loj. Macroevolution, piv txwv li, yog siv los hais txog kev hloov pauv ntawm cov kab mob uas tseem ceeb txaus uas, dhau sijhawm, cov kab mob tshiab yuav raug suav tias yog hom tshiab nkaus xwb
